Nothing is perfect. So neither are speakers.
Practically, the sound coming from a speaker might be said to be "perfect" when the listener thoroughly enjoys what they hear without reservations. After, all the speakers job is to deliver pure musical enjoyment. Knock on wood, that is what I find these days listening to to my OHM 5s. Pure musical enjoyment! Nothing to detract from the pure musical enjoyment. So I gotta say I feel that they do their job perfectly. I have 4 other pair of speakers set up to run concurrently in my home. I enjoy them all, but I can easily find some reservations in some cases listening to the others.
It doesn't matter really matter if in fact speakers are or are not perfect (they are not), if even there was a way to determine such things reliably and without debate.
